MathProblem-Solving and Data AnalysisHard
A store raises the price of a jacket by 20%. Later, it lowers the new price by 20%. The final price is what percent of the original price?
A80%
B96%Correct
C100%The trap
D104%
Check with $100: $100→then$120→then$96
Turn each change into a multiplier.
Up 20% means × 1.20. Down 20% means × 0.80.
Apply them in order.
1.20 × 0.80 = 0.96
Read the answer.
The final price is 96% of the original. That’s B.
Why not 100%?
The 20% cut is taken from the higher price, so it removes more than the 20% increase added.

98 questions across four modules, in the digital SAT’s order: Reading & Writing Module 1 and Module 2 (27 questions each), a 10-minute break, then Math Module 1 and Module 2 (22 questions each). On official timing that’s 2 hr 14 min of testing. You get estimated section scores and a total at the end.
Yes. In the standard full-length tests, Module 2 of each section is the harder version if you get 60% or more of Module 1 right, and the easier version if you don’t. Challenge tests use the hardest material throughout.
Official timing, extended 1.5× time, or untimed, on every test, including the free ones. Extended time allows 48 minutes for each Reading & Writing module and about 52 for each Math module. Untimed removes the clock so you can focus on accuracy.
A quick run with three hearts. Each right answer builds your streak: the questions get harder as it grows, and your points multiply (×2 from three in a row, ×3 from six). A miss costs a heart and drops you back to easy. Best is your longest streak.

Command of Evidence (Textual) · Lesson 1
Pin down the exact claim
Every finding question starts with a claim, usually a hypothesis: an explanation a researcher has proposed but not yet proven. Before you read the choices, say that claim back to yourself as precisely as you can.
Break it into parts. What is it about? What happens, or what causes what? Compared with what? And when, where or for whom? Take the hypothesis Tomato plants given a new fertilizer grow taller than plants given none. It is about tomato plants, the effect is growing taller, and the comparison is with plants given no fertilizer.
On a support question, the right answer is the finding that, if true, would make that exact claim more likely. (Weaken questions reverse this; Lesson 2 shows how.) It never swaps in a different subject, effect, comparison or scope: if the claim compares two groups, the finding covers both, measured the same way. Some findings support a claim by confirming the reason or mechanism it depends on (Lesson 3). Most directly means the finding speaks to the claim itself, not to something next to it.
Treat every choice as true. The question says if true, so never reject a finding because it sounds unlikely or surprising. Ask only one thing: if this were true, what would it show about the claim?
| Part | Ask | Fertilizer example |
|---|---|---|
| Subject | What or whom is it about? | Tomato plants |
| Effect or relationship | What happens, or what causes what? | The fertilizer makes them grow taller |
| Comparison | Compared with what? | Plants given no fertilizer |
| Scope | When, where or for whom? | Any limits the passage states, such as one region or one season |
Worked example Easy
Hermit crabs live in empty snail shells and must move into larger shells as they grow. Marine biologist Tomasz Wierzbicki has watched hermit crabs on a rocky coast trade shells many times. He hypothesizes that when the crabs choose a new shell, they choose based on how well it fits their body size rather than on the shell's color or pattern.
Which finding, if true, would most directly support Wierzbicki's hypothesis?
- Hermit crabs on the coast change shells about three times as often in the warm summer months as they do in the colder and stormier winter months of the year.
- When offered a choice of empty shells, the crabs picked shells that fit their bodies closely, whether the shells were plain or brightly patterned.Answer
- Brightly patterned shells are less common on the coast than plain shells are.
- Some of the crabs Wierzbicki watched kept the same shell for several months.
How to solve it
- Pin down the claim. Subject: crabs choosing a new shell. What decides the choice: how well the shell fits the crab's body. Comparison: rather than the shell's color or pattern.
- So the right finding shows crabs choosing by fit and ignoring color and pattern.
- Only the second choice does both: the crabs picked well-fitting shells whether the shells were plain or brightly patterned. The other choices are about hermit crabs and shells, but none shows how a crab chooses.
Why each choice is right or wrong
- A. Incorrect. This finding is about when and how often crabs change shells, not how they choose one. It says nothing about whether fit, color or pattern decides the choice.
- B. Correct. The crabs chose by fit, and the shell's color or pattern made no difference to the choice. That is exactly what the hypothesis says.
- C. Incorrect. How common each kind of shell is on the coast says nothing about how crabs choose among the shells they find. Plain shells could be more common whether crabs choose by fit or by pattern.
- D. Incorrect. Keeping a shell for months tells you how long a crab stays in a shell, not what it looks for when it picks a new one.
Worked example Medium
In 2022, the public libraries in the city of Harlow Bay began closing at 10 p.m. instead of 7 p.m. Sociologist Amara Okafor hypothesizes that the longer evening hours increased teenagers' library visits by a larger percentage than they increased adults' library visits.
Which finding, if true, would most directly support Okafor's hypothesis?
- In the year after the change, the total number of evening visits to the libraries rose by about 15 percent.
- In the year after the change, visits by teenagers to the city's libraries rose.
- In the year after the change, visits by teenagers rose by about 30 percent, while visits by adults rose by about 8 percent.Answer
- In a survey taken the year after the change, most teenagers in Harlow Bay said they would like the libraries to add more study rooms and quiet spaces.
How to solve it
- Pin down the claim. Subject: library visits after the longer hours. Effect: an increase. Comparison: the percentage increase for teenagers is larger than the percentage increase for adults.
- A claim with larger than has two sides, so the right finding must give information about both teenagers and adults, measured the way the claim measures them: as percentage increases.
- Only the third choice compares the two groups, and it shows the teenage rise (about 30 percent) larger than the adult rise (about 8 percent).
Why each choice is right or wrong
- A. Incorrect. A 15 percent rise in total evening visits could come mostly from teenagers, mostly from adults or equally from both. It doesn't separate the groups, so it can't test the comparison.
- B. Incorrect. This finding is tempting because it matches half the claim: teenage visits rose. But it says nothing about adult visits, so it can't show that teenage visits rose by a larger percentage.
- C. Correct. The finding covers both sides of the comparison and shows a larger percentage rise for teenagers than for adults, which is exactly what the hypothesis predicts.
- D. Incorrect. This is about what teenagers would like the libraries to add, not about how many visits they made after the hours changed.
Trap The right topic, but no test of the claim
A choice can mention the exact people, place or thing in the passage and still say nothing about the claim. Hermit crabs changing shells more often in summer is about hermit crabs and shells, but not about how they choose. Ask what the choice would show, not what it mentions.
Trap Half the claim
When a hypothesis compares two groups, such as more than or less than, a supporting finding has to speak to both, measured the way the claim measures them. A finding that teenage visits rose, with nothing about adults, leaves the comparison untested. When a hypothesis picks one explanation rather than another, the right finding has to tell the two apart.
Practice
Choose a section, then practice a whole domain or drill a single skill.
Full-length tests
Each test mirrors the digital SAT: 98 questions across four modules, 2 hr 14 min on official timing.
A little harder than the real SAT. These tests can run slightly tougher than test day, which makes them good practice: if you can handle these, the real one should feel easier. No question appears in more than one test, Challenge Tests included.
Challenge Tests Hardest of the hardest
Same 98-question format, but every question is drawn from the toughest SAT material: Challenging-tier math throughout and the hardest reading.
